\"\"Rarely has there been so much talk about \u2018ventilation\u2019 as in the past and current year. No wonder, since the exchange of air in rooms was and still is considered a tried and tested means against potential corona virus load caused by infectious aerosols. So far, there is no measuring device that is able to prove the contamination of indoor air by SARS<\/em>-CoV-2. However, it is possible to determine a necessary ventilation interval via the \u2018detour\u2019 of a permanent measurement of CO2 values. Because the more people are in living rooms, office spaces, production rooms, schools and daycare centres, the more the exhaled carbon dioxide level increases \u2013 to the point of a CO2 alarm: time to open all the windows!<\/h2>\n

<\/p>\n

Every person needs around 12,000 litres of breathing air each day, metabolising oxygen in their body into carbon dioxide (CO2). As a result, the air that we breathe out has 4% less oxygen – but 4% more CO2. No problem, as long as we are outdoors. However, in closed room, the life-giving oxygen in the air is quickly depleted. We react to the continuous increase in the proportion of CO2 with an increased susceptibility to fatigue and a significant loss of performance. It is therefore advisable to continuously monitor CO2 values in closed rooms with climate measuring devices such as the air quality monitor BZ30, the professional air quality data logger BZ30 <\/strong><\/a>or the particle measuring device BQ30 <\/strong><\/a>from Trotec- especially in public facilities such as daycare centres and schools, but also in private households. This ensures a sufficient supply of oxygen in good time, provided that the ventilation behaviour is correct. At the same time, this also reduces the pollution of indoor air by corona virus.<\/p>\n

How to ventilate correctly \u2013 according to DIN standards 1946-6<\/h3>\n

Just open all the windows to ventilate? Practice shows that it is not that simple, especially during the cold season. Incorrect ventilation actually worsens the air quality indoors and also wastes valuable heating energy. This is why the \u2018correct\u2019 ventilation according to the standard of the German Institute for Standardisation (DIN) has proven its worth: the DIN standard 1946-6 specifies how often and more importantly how long fresh air should be allowed into the room in order to guarantee a perfect indoor climate.<\/p>\n
